Application Overview 2-16# MultiFunction Input Commands - nviOpCommandsBit 2, bit 3, bit 4, bit 5 and bit6 of this network variable control the multifunction input commands, as described below. These commands areequivalent to contact closures on external terminals S3 – S7, respectively. Function selection for the multifunction inputs are configured inparameters H1-01 through H1-05.Table 2.20 – Multi-Function Input Commands - nviOpCommandsbit # Point Description Off (0) State On (1) State Default2 Multifunction Input 1 Command Depends on Terminal S3 function selection Depends on Terminal S3 function selection Off3 Multifunction Input 2 Command Depends on Terminal S4 function selection Depends on Terminal S4 function selection Off4 Multifunction Input 3 Command Depends on Terminal S5 function selection Depends on Terminal S5 function selection Off5 Multifunction Input 4 Command Depends on Terminal S6 function selection Depends on Terminal S6 function selection Off6 Multifunction Input 5 Command Depends on Terminal S7 function selection Depends on Terminal S7 function selection Off# Terminal S1 Safety Interlock ControlIn certain applications, a normally closed safety interlock may be connected to the driveís terminals S1 and S2. When the connection betweenS1 and S2 is broken, the drive will automatically stop. The drive Run will restart once the connection is re-established. Refer to the appropriatedrive user, programming and/or technical manual for the proper use and wiring of a safety interlock circuit. If a safety interlock is not used, ajumper must be present between terminals S1 and S2.For E7B and E7L units refer to the schematic and instructions that came with the unit, along with the appropriate technical manual.
